The Adventurers had a special "airborne world premiere" on February 23, 1970, as the
in-flight movie of
Trans World Airlines' first
Boeing 747 Superjet flight between
New York City and
Los Angeles, with the film's stars and members of the press aboard. It marked the first time that a movie and a plane premiered in the same event. Additional test screenings occurred on March 4, 1970, at the DeMille Theatre in New York City and the Fox Village Theatre in
Westwood, California. Arthur D. Murphy of
Variety called it "a classic monument to bad taste ... marked by profligate and squandered production opulence; inferior, imitative and curiously old-hat direction; banal, ludicrous dialog; sub-standard, lifeless and embarrassing acting; cornball music; indulgent, gratuitous and boring violence; and luridly non-erotic sex."
Gene Siskel of the
Chicago Tribune gave the film 1 star out of 4 and wrote, "'The Adventurers' has nothing to recommend it. It is not erotic. It is not funny. It is violent to the point of obscenity and is as much the story of why film companies are losing millions as it is the story of Harold Robbins' best-selling novel."
Kevin Thomas of the
Los Angeles Times stated that the film "is blatant in its borrowing from the more sensational headlines and naked in its manipulation of emotions to the susceptible," adding that "Gilbert is nothing if not consistent: the acting and the relentlessly risible dialogue are uniformly terrible." Gary Arnold of
The Washington Post wrote, "Unfortunately, Lewis Gilbert's film version of the novel is quite faithful to the letter and spirit of the original. It alternates from slaughter to torpor to sex to torpor and back again to slaughter. Whatever the mode, the scenes are usually hideous or clumsy on their own terms and useless as clues to subsequent events or the characters' motives."
The Monthly Film Bulletin called it "A three-hour slog through every imaginable cliché of writing and direction" and further remarked, "This might be described as the film with everything; trouble is, it is difficult to imagine anybody wanting any of it." Cotes said in 1992 "I loved the film. I know it was full of bad taste and things like that, but it was meant to be. If you’re doing blatant bad taste, it had everything." Paul Mavis, reviewing the Warner Archive DVD release for Movies & Drinks, enjoyed its outrageousness, stating
The Adventurers is, "part
faux-David Lean, part lurid comic book with funny accents and naked breasts--and all of it an irresistible, frequently maddening mess." He believes that the mixing of Third World politics and jet-setting was inspired by international playboy
Porfirio Rubirosa. Director Lewis Gilbert said on June 25, 2010, on the BBC radio program
Desert Island Discs, that
The Adventurers was "a big, sprawling, very expensive film which was a disaster. I should never have made it. It's one I'm not proud of." ==Home media==
